It is to be noted, however, that the appended drawings illustrate only illustrative embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.

FIGS. 1A to 1H depict a tab, including as associated with pocket fabric;

FIG. 2 is the back side of an electronic device, as shown in a pocket; and

FIG. 3 is a complementary surface comprising material B and having a rim.

To facilitate understanding, identical reference numerals have been used, where possible, to designate comparable elements that are common to the figures. The figures are not drawn to scale and may be simplified for clarity. It is contemplated that elements and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

DETAILED DESCRIPTION

FIG. 1A shows a tab 20 placed on fabric 200 from a pocket by its adherence/retention via a retainer. The retainer can be located on the inside of the pocket or the outside. Accordingly, the tab can be visible on the outside of the pocket, or can be located within the pocket. In one embodiment, retaining notch 12 (FIG. 1B) is configured in interact with the retainer. FIG. 1C shows the cross-section of an embodiment of a retainer 30, interacting with the tab 20, forming a tab device 22. FIG. 1D shows an embodiment of a retainer 30 which is a clip, such as a metallic clip.

FIG. 2 shows an electronic device 100 with camera lens 110 and a structure 120 including material B (defined below). Shown is a side of the electronic device away from that with a view screen (not shown). Illustrated is a pocket 200 with the exemplary system in use.

At least a portion of the tab complex 22 is of material A. Materials A and B are such that one is magnetic, and the other is attracted by a magnet (magnetically susceptible). Materials A and B can both be magnetic, so long as care is taken with the N and S poles so that the materials attract.

FIG. 3 shows a portion of a structure (such as in FIG. 2) with material B with a protruding retaining rim 122. The retaining rim defines a retention zone within its border. The rim act so as to provide further resistance to a tab complex 22 sliding out of the retaining zone. The rim can be wider and/or surround the zone where adhesion to material A will be effected. The rim portion may or may not be of material B.

The tab can be circular, rectangular or any other shape that allows for a useful retaining notch. If for example the tab is rectangular, the notch can manifest in the corners to provide good retention. Note that in this application “notch” is used in the singular, but such a “notch” can manifest in multiple segments of canal.

More than one tab can be used on a pocket, In embodiments, two or more tabs are joined by an exterior (to the pocket) bridging structure, which can be decorative. In embodiments, the exterior of the tab is coated (such as by, without limitation, electroplating) to provide an aesthetic effect.

The retainer can be of a soft material such as nylon. Such a material provides the advantage that it is less likely to scratch the electronic device—especially where the electronic device is by mistake placed in the pocket with the view screen facing the tab. The material should be elastic enough to be stretched over the rim of the notch.

A wire ring, or a plastic coated wire ring can be used, with for example a portion of the wire twisted to tighten it about the tab. The notch can include a portion of greater depth into which the twisted portion can be folded.

In embodiments, the retainer is magnetically attracted to the tab. Such that retainer is on one side of the shirt material, and the tab on the other. If the tab is on the inside, it can for example comprise magnetic material, and attract a magnetically susceptible material with the electronic device. Or, it can be magnetically susceptible and (i) be attracted to magnetic material in the electronic device or (ii) be surrounded by magnetic material in the retainer that attracts both the tab and a magnetically susceptible part of the electronic device.

FIGS. 1E and 1F show a fabric side, and side view, of a tab with a hollow into which fits a retainer 30′, typically from the other side of the fabric. In embodiments, the retainer 30′ is attracted to the tab 20 magnetically.

Where there is a tab or retainer on the interior of a pocket, it can be coated with soft plastic to help protect the electronic device (unless already of a soft material). The tab or retainer can be fully coated, or coated on the side configured to contact the electronic device.

FIGS. 1G and 1H show a fabric side, and side view, of a tab with a hollow into which fits a retainer, and a channel 14 into which the retainer is configured to expand, such as at three points or uniformly. For example, the retainer can include a push button that actuates three or more levers or cams that are for example spring loaded in closed position but can be locked into expanded position. Or, the push button mechanism can for example expand an o-ring into the channel 14. In an embodiment, the retainer has levers or cams (or the like) or an o-ring that snaps into the channel 14 when the retainer is inserted into the hollow. Release (if there is release) can be for example by temporarily deforming the tab to push the retainer out. The magnetic element can be the tab or the retainer.

A metal retainer can be used, for example with a crimping device—such as used to retain PEX piping to connector pieces.

The material A or material B can be a plastic infused with magnetic or magnetically susceptible material.

In an embodiment of the invention, the tab has one or more short pins configured to pierce the fabric of the pocket, and the retainer comprises a device such as a clip for retaining the pin by compression.

In a simple form of the invention, the tab is retained on the outer surface of the pocket by the magnetic attraction to material B. In this form, a single magnet as the tab has been found effective to retain a Samsung S2 phone with over-size battery when dipped to an angle at which the cell phone would otherwise drop out of the pocket.

All ranges recited herein include ranges therebetween, and can be inclusive or exclusive of the endpoints. Optional included ranges are from integer values therebetween (or inclusive of one original endpoint), at the order of magnitude recited or the next smaller order of magnitude. For example, if the lower range value is 0.2, optional included endpoints can be 0.3, 0.4, . . . 1.1, 1.2, and the like, as well as 1, 2, 3 and the like; if the higher range is 8, optional included endpoints can be 7, 6, and the like, as well as 7.9, 7.8, and the like. One-sided boundaries, such as 3 or more, similarly include consistent boundaries (or ranges) starting at integer values at the recited order of magnitude or one lower. For example, 3 or more includes 4 or more, or 3.1 or more. If there are two ranges mentioned, such as about 1 to 10 and about 2 to 5, those of skill will recognize that the implied ranges of 1 to 5 and 2 to 10 are within the invention.

The invention can be further described with reference to the following numbered embodiments:
